Project Idea

[noamanabdulghaffar0]

I have an idea regarding designing solar powered bin that will operate along the coast of the beaches to clean up plastic that is floating on the top.
So according to my idea the solar panel will automatically adjust itself changing its direction to face the sun in order to generate max power and the bin will have some sort of sensor installed that will detect plastics and with the help of the pump the plastics go inside the bin and get collected inside the filter that is in the bin.

Can anyone suggest how can I begin the coding to control how the bin operates and detects plastic floating on top of water?
